SPECIFICATION forming part of Letters Patent No. 554,409, dated February11, 1896. Application filed October l0, 1893. `Renewed August 19,1395.Serial No. 559,798. (No model.)

.To all whom. t may concern.-

Be it known that l, CHANNING WHITAKER, a citizen of the United States,residing at Tyngsborough, in the county of Middlesex and Commonwealth ofMassachusetts, have invented certain new and useful Improvements inFly-Frames, of which the following is a specification, reference being`had therein to the accompanying drawings.

My invention relates to spinning-machines of the class known asfly-frames. The first part thereof relates to the devices which areknown as tension-1notio11s and are employed in fly-frames for thepurpose of communicating movement to the cone-rack and its connectedbelt-guide, in order to shift the cone-belt along the cone-pulleys, asis required during the filling of the bobbins. Various arrangements oftransmitting-gearing Aand connections have been devised for the onto theloose pulley upon the said shaft, for

the purpose of stopping the machine, a break or disconnection shall beoccasioned in the rack-actuating train, all as will be understood bythose skilled in the art, and for well-known purposes. United StatesLetters Patent No.

A51.845776, granted October 25, 1892, may be revidi? for cfnicnient andready change in the vices. .plan and partly in horizontal section..

said gearing such as will enable the rate of advance of the cone-rack tobe varied as required, to provide in a convenient manner for occasioninga break or disconnection in the said gearing through the action of thestopmotion devices, to provide for ready re-engagement of the gearingafter a break or disconnection, and to guard against an unintentional orundesired change in the relative position of one gear .with respect toits mate through the space occupied by one or more teeth in consequenceof the break or disconnection and recoil in the gearing.

The second part of my invention relates to the winding-up devices, socalled, which are employed in fly-frames for the purpose of effectingthe return of the cone-rack to its starting position in the ily-frameafter a set of bobbins has been filled to the desired eX- tent withrovings, in order, by means of the cone-belt guide carried by thecone-rack, to lead the cone-belt back to the starting ends of thecone-pulleys,preparatory to beginning to wind upon a fresh set ofbobbins. The object of this part of my invention is to provide forautomatically connecting the said windup devices with the cone-rack whenthe iiy-frame is stopped through the action of its automatic stop-motiondevices, and for automatically disconnecting them therefrom when thefiy-frame is restarted.

My present invention consists in certain novel constructions andcombinations of parts, which I shall now proceed to describe withreference to the accompanying drawings, in which latter are presentedthe best embodiments thereof that have yet been devised by me, afterwhich the characteristic features of the invention will be particularlypointed out and clearly defined in the claims at the close of thisspecification.

In the drawings, Figure l is a view, mostly in rear side elevation butwith portions of the machine-framing in vertical section, of part of aily-frame with the first part of my invention applied thereto,sufficient of the iiyframe being shown to render evident the relationsand connections of my improved de- Fig. 2 is a view of the same partlyin Fig. 3 is a view in plan of certain supports here- IOO inafterdescribed, part of the machine-framing being in horizontal section. Fig.4 is a view in vertical section on line 4 4 of Fig. 2. Fig. 5 is adetail view in vertical section on line 5 5 of Fig. 1. Figs. 0 and 7 aredetail views of the driving-pinion on the tumblingshaft, Fig. 0 being inside elevation and Fig. 7 in inverted plan. Fig. 8 is a partly sectionaldetail view showing parts of the connections whereby the driving-pinionon the tumbling-shaft is moved lengthwise of the said shaft. Fig. 9 is aView similar to Fig. 1, but including the second part of my invention.Fig. 10 is a detail view illustrating a modification relating to thesecond part of the invention.

In the drawings, l is the tumbling-shaft of a iiy-frame.

3 is the cone-rack.

4 is a pinion in engagement with the teeth of the cone-rack 3.

5 is a gear turning in unison with the pinion 4.

0 is a carrier-pinion meshing with the gear 5.

7 is a carrier-gear above the carrier-pinion G and connected with thelatter so as to turn in unison therewith, and 8 is a driving-pinionrotating with the tumblingshaft and meshing with the carrier-gear 7.

The pinion 4 and gear 5 are both fixed upon the short shaft 2, (see Fig.4,) which at its lower end is stepped in the bearing 104, formed in theswinging arm 10, concentric with the aXis on which the said arm turns,as shown most clearly in Figs. 3 and 4.

Through the described gearing, which, as shown, is made up of spur-gearsand pinions, and which it is preferred should be constituted andarranged substantially as is shown, motion is transmitted automaticallyand intermittently from the tumbling-shaft 1 to the cone-rack 3 duringthe regular working ot the y-frame, and thereby the cone-rack is movedendwise gradually to shift the conebelt upon the cone-pulleys, as willbe understood. Obviously, a greate-r number of spurgears and pinions maybe employed in the transmitting-train, if desired, although I prefer thesimple Atrain shown in the drawings.

The carrier-gear 7 is a change-gear, and one size of such gear may besubstituted for another, as may be required in order to transmit motionat the desired rate of speed from the tumbling-shait 1 to the cone-rackFor the purpose of enabling the carrier-gear 7 to be removably connectedwith the carrier pinion 6 any suitable known form of connections may beused. I have shown (see Fig. 4) the hubGl of the carrier-pinion Gextended for the reception thereon of the carrier-gear 7, and providedwith a pin 02, which compels the carrier-pinion and carrier-gear to turnin unison, the carrier-gear being kept on the said hub by a nut 03,which is turned on the threaded upper end of the hub. As shown mostclearly in Fig. 4, the connected carrierpinion and carrier-gear turnupon the stud 9,

which latter is provided with a iiange 91, on which the lower side ofthe carrier-pinion rests, and they are held from rising on the said stud9 bymeans of a screw 92, the threaded stem of the said screw entering athreaded hole in the end of the stud 9, and the edge of the iiat head ofthe screw overlying the upper end of the hub of the carrier-pinion 0.The stud 9 is mounted on the swinging arm 10, which swingsconcentrically with the gear 5 and the pinion 4, the stud having itslower end passing through a hole 101 in the arm, and a nut 93 being`placed upon its projecting threaded end and turned up tightly, a washer94 being interposed between said nut and the under side of the arm 10.The arm 10 is provided with a journal 102, that is fitted to a bearingin a lug or lateral extension 11 on the cross-piece 12, forming part ofthe framework of the machine. The lower end of the journal 102 isthreaded and projects below the bearing in the lug or extension 11, itreceiving thereon the washer 1022 and the nut 103. After the arm 10 hasbeen adjusted into the position required by the particular size ofchange-gear that it is designed to use it may be secured in suchposition bytightening up the nut 103. I prefer, however, to employ inaddition the bolt 1091, (shown in Figs. 1, 3, and 4,) with its washer1092 and nut 1093. The said bolt is passed through a hole in the arm 10and through a slot 1094 that is formed in the cross piece 12, the saidslot being formed concentric with the axis on which the arm 10 swings,as shown clearly in Fig. 3.

In order that, when desired, a break or disconnection may be occasionedin the gearing intermediate the tumbling-shaft and the conerack, I mountthe driving-pinion 8 upon the tum bling-shaft 1,with capacity formovement endwise of the latter, and connect the said pinion with thetumbling-shaft by'a spline '13, Figs. 1 and 5, or the known equivalentthereof, so as to compel it to rotate in unison therewith. This enablesthc driving-pinion S to be moved along the shaft until it is out of meshwith the change-gear 7, and afterward to be reversely moved and'placedagain in mesh therewith. W'ith the object in view of moving the pinion Sautomatically at the proper times I connect the same with the stopmotiondevices in the following manner:

At 14 is part of the stop-motion lever and at 15 the weight hungthereon. rod having its upper end pivotally connected with the saidlever 14 and its lower end passed through a hole in one end of a lever17, the other end of the said lever being formed or provided with a fork171, having projections 172 172, Fig. 5, preferably constituted by screwstuds, as shown, which enter a groove 81 in the hub of the pinion 8 onthe tumbling-shaft. A collar 19 is mounted on the rod 10 above the lever17 and it is held in the desired position of adjustment thereon by.means of a clamping-screw 20, which passes through the collar and takesbearing At 10 is a- IOO by its end against the surface of the rod. Aspiral spring 21 is placed on the portion of the rod 16 which extendsbelow the lever 17, and is held thereon and kept at the desired degreeof compression by means of the nuts` Vthe automatic stopping devices aremoved in the manner that is required for starting the ily-frame, thelever 17 is acted upon so as to cause the pinion 8 to be slid along thetumbling-shaft and again placed in mesh with gear 7. The spring 21 willyield, so as to avoid breakage, if this reverse movement of the pinion 8is prevented or interrupted-as,

`for example, if a tooth or teeth thereof should strike against a toothor teeth of the changegear 7 in such manner as to arrest the saidmovement. The position normally occupied by the pinion 8 relatively tothe change-gear 7, when in working engagement with the latter, isdetermined by the shoulder 139 at the lower end of spline 13, as shownin- Fig.

5, the said shoulder acting as a stop to limit the descent of pinion 8when the rod 16 is drawn upward so as to compress spring 21 against theunder side of the left-hand arm of lever 17. The collar 19 is placedhigh enough on rod 16 to provide sui'iicient play to enable the pressureof the spring 21 to carry the pinion 8 into proper contact with shoulder139.

In some cases I shall make the teeth of the carrier-gear 7 and thedriving-pinion 8 sharp or pointed at the upper side of the saidcarrier-gear and lower side of said driving-pinion and of slightlygreater breadth than usual, as is shown in Figs. 1, 6, and 7. I preferthis form of the said teeth. It facilitates re-engagement of the teethof the driving-pinion S with those of the carrier-gear 7 after adisconnection or disengagement, as will be apparent7 and to such anextent does it lessen the danger of the movement of pinion S toward itsnormal working position becoming prematurely arrested in the mannerhereinbefore set forth that I contemplate omitting, sometimes, thespring 21 or other equivalent yielding arrangements.

Again, when pinion 8 is drawn out of mosh with gear 7 there usuallyoccurs a slight recoil of the transmitting-gearing. lith teeth onpinionS and gear 7 shaped as usual this recoil, even when less in extentthan a tooth of gear 7, might occasion the loss of a tooth in therotation of the said parts, for it might shift the position of the gear7 backwardly, so that the teeth of the latter would prevent pinion 8from descending until, at the begin` By the reverse sented at 25.

ning of the next movement of rotation of pinion S, the teeth of thelatter became shifted into proper position over the space of the gear 7.The pointed form of the teeth guards against this loss, for unless therecoil is enough to carry the point of a tooth on the gear 7 rearwardlypast the point of the corresponding tooth on the pinion S the points ofthe teeth on each wheel will be guided back into the same spaces on theother wheel that were before occupied. In Fig. G one tooth of gear 7 isshown at av, it being represented in the position which would beoccupied by it if, in consequence of the disconnection, gear 7 weremoved backwardly by the recoil a distance equal to part of the width ofa tooth. As will be seen, tooth a; will slide readily into the' originalspace when pinion 8 is depressed. The pointed form of teeth permits therecoil to begin and continue gradually as the teeth on pinion S aredrawn out of those of gear 7, and this causes a control to be exercisedover the recoil until the separation is complete, thereby lessening theextent of the recoil.

rIhe illustrated combination and arrangement of gearing is very simple.All of the gears are spur-gears- There are but three points therein atwhich the teeth of the rack and gears intermesh with each other. Thechange-gear is the gear in contact with the pinion on thetumbling-shaft. A difference of one tooth in a change-gear located atthis point obviously will have less eifect upon the movementcommunicated to the cone-rack than the like difference in a change-gearlocated at some point nearer the cone-rack. From this it follows that afiner adjustment maybe secured through my devices than has been securedby the devices with which I previously have been. acquainted. Itfollows, also, that if a tooth or teeth should be lost through recoil ofthe parts in consequence of the disengagement of the driving-pinion 8from the carrier-gear 7 the effect will be minimized so far as concernsthe extent to which the cone-rack is thereby altered in its position.

Fig. 9 illustrates the character of the second part of my invention andone means of reducing the same to practice. parts are shown in Fig. 9that are shown in Fig. 1, and, in addition, there are shown in theformer the wind-up shaft and certain clutching and unclutching devicesthat are combined with the said shaft. The wind-up shaft is representedat 23, the hand-wheel thereon at 24, and the gear on the said shaftwhich meshes with the cone-rack is repre- As is well known to thoseskilled in the art, the cone-rack-actuating devices move the cone-rackgradually endwise in a fly-framelas the bobbins iill with roving.

When the desired amount of roving has been wound upon the bobbins theiiy-fra1ne is stopped,- and in preparing to restart with a fresh set ofempty bobbins the cone-rack is returned to its starting position inorder to replace the cone-belt on the starting ends of the IIO The same4 cone-pulleys. It is customary to effect this return by hand by meansof the wind-up shaft, the latter being turned by mea-ns of itshand-wheel 24. The constructionheretofore in use is such that the wind-up shaft always, so far as known to me, has remained in operative gearconnection with the conc-rack, and hence the said shaft has had movementof rotation communicatedthereto from the conerac t as the latter hasbeen advanced by its actuating devices in the regular working of thefly-frame. This movement of rotation thus communicated from thecone-rack to the wind-up shaft is needless, and there is, therefore, anunnecessary and unproiitable expenditure of energy. Accordingly,proceeding on the basis that the wind-up shaft is required to be inoperative connection with the cone-rack only at such times as it is tobe employed in effecting the return of the cone-rack to its startingposition, which is only after the regular operations of the machine havebeen arrested, I have so arranged and combined the parts that thewind-up shaft shall normally be kept out of operative connection withthe cone-rack, and shall be thus held while the fly-frame is at work,and also that, when the operation of the machine is arrested through theaction of the automatic stop-motion devices thereof, the wind-up shaftshall be placed in operative connection with the cone-rack., in orderthat it then may be employed for moving the latter by hand, as required.Thus in Fig. 9 the gear 25 is loose upon the wind-up shaft 2 3, andturns idly thereon. as the rack is advanced by its actuating devices inthe regular workin g of the flyframe. The said gear is provided orformed with one half ormember of a clutch, as shown, while the opposinghalf or member 251 of the clutch is splined upon the wind-up shaft Thesaid half or member 251 is engaged by projections 179 (preferablyconstituted by screw-studs) from the adjacent end of the lever 17, asshown. Thereby as the lever 17 is moved by the stop-motion lever laitmoves the clutch half or member 251 on the wind-up shaft 23, in additionto moving the drivingpinion 8 on the tumbling-shaft, as hereinbeforedescribed. In the descent of the stopmotien lever 1-1 the wind-up shaft23 and its gear 25 are clutched together so as to place the wind-upshaft in operative connection with the cone-rack, and simultaneouslytherewith is effected the disengagement of the driving-pinion S from thecarrier-gear 7, this last leaving the cone-rack free to be moved by handby turning the wind-up shaft. IVhen the stop-motion lever is raised intothe position which it occupies during the running of the y-frame, theclutch member 251 is raised simultaneously with the depression of thedriving-pinion 8.

Fig. 10 shows a modification in which the gear 25 is free to slidelengthwise of shaft 23, being caused to turn therewith by spline 2G, andis enga-ged by the adjacent end of lever 17 so as to be moved up anddown by the said lever. In this modification the lower sides of theteeth of gear 25 and the upper sides of the teeth of the cone-rack aremade pointed, similarly to the teeth of drivin g-pinion 8 and gear 7,and with the same reasons in view as in the case of the latter.

An application for a patent for improvements in fly-frames filed by meOctober 10, 1893, Serial No. 487 ,7 7 O, presents an arrangement ofmechanism embodying a wind-up shaft which is held normally in a positionin which it is out of gear connection with the cone-rack, the said shaftbeing moved bodily by hand when it is desired to prepare to wind up, inorder to place the same in operative connection with the cone-rack. Icontemplate combining such a movable wind-up shaft with other devicessubstantially like those which are presented in this case, for thepurpose of moving the shaft by connections with the automaticstop-motion devices of the flyframe. Inasmuch as it will be readilyapparent how such combination is to be produced, it appears unnecessaryto show the same.

lVhile herein I have shown and described the driving-pinion 8 as mountedwith capacity to move lengthwise of its shaft for purposes ofdisconnection, it is to be understood that I regard it as being withinthe broadest aspect of my invention to arrange so that some other gearor pinion in the transmitting-train between the tumbling-shaft andcone-rack shall thus be lmoved for t-he said purpose.
